While the Craw are relatively peaceful crustaceanoids, the miliant Craydeen are anything but. Stronger and nastier than their arthropoidal cousins, The Craydeen are rampant speciesists who bully, torment, and enslave "lesser races" at every opportunity.

The Craydeen are nomadic and semi-aquatic, and live as brigands and pirates. They are also polyglots who can comprehend and commune with all sentient mutant species.

Craydeen love Ancient carbonated beverages, and will do anything to acquire them.
